Lithographic apparatus and device manufacturing method

A system and method to manufacturing a device provide a substrate and perform at least one exposure step. Each exposure step projects a patterned beam of radiation, which was patterned using an individually controllable elements, onto a target portion of the substrate. The projected patterned beam includes a plurality of pixels. Each exposure step also: (a) ordinarily controls the elements, such that each pixel delivers a radiation dose no greater than a predetermined normal maximum dose to the target portion in the exposure step; and (b) exceptionally controls the elements, such that at least one selected pixel delivers an increased radiation dose, greater than the normal maximum dose. The increased dose may be delivered to compensate for the effect of a defective element at a known position in the array on a pixel adjacent a selected pixel. Alternatively, it may compensate for underexposure of the target portion at the location of a selected pixel resulting from exposure of that location to a pixel affected by a known defective element in another exposure step. The invention uses doses up to the predetermined normal maximum for normal printing, but reserves at least one increased dose for compensation purposes. Accordingly, even when a dead black pixel falls in the middle of a group of surrounding white pixels it can be compensated for by increasing the radiation dose delivered by one or more of those neighboring white pixels, above the normal fully white value.

Application of total triterpenoids of Pteridocarpus in protecting chronic alcoholic liver injury

The invention discloses the application of total triterpenoids of Pteridocarpus to protect chronic alcoholic liver injury, and belongs to the technical field of biomedicine. A dose-escalating drinking method was used to simulate the process of chronic alcohol-induced liver injury in humans. The total triterpenoids of Pteridocarpus can inhibit GOT and GPT to a certain extent, and the inhibitory effect is positively correlated with the dose. The purified total triterpenoids of Viburnum fern have strong antioxidant capacity in vivo, and its hepatoprotective mechanism may be to effectively alleviate the damage caused by alcohol to the liver by enhancing the body's antioxidant capacity and effectively removing unfavorable free radicals. Medium and high doses of purified total triterpenoids of Viburnum fern can effectively alleviate the oxidative damage caused by lipid peroxidation and free radical attack in the liver, reduce the degree of hepatocyte enlargement, necrosis and fatty degeneration, and regulate cells to restore normal metabolism and Physiological function, its effect is better than that of the positive control drug bifendate within a certain concentration range, indicating that the total triterpenoids of Pteridocarpus have a certain protective effect on chronic alcoholic liver injury.
